Question

YOU ARE GIVEN A MAGIC PENNY ON THE DAY YOU ARE BORN. YOU ARE TOLD THAT EACH YEAR ON YOUR BIRTHDAY, THE PENNY WILL MAGICALLY DOUBLE IF YOU DONT SPEND IT . HOW MUCH MONEY WILL YOU HAVE ON UR 10TH BIRTHDAY?

Answer 1

If the penny doubles every year, then on the 1st birthday, the penny will become 2 pennies, on the 2nd birthday it will become 4 pennies, on the 3rd birthday it will become 8 pennies, and so on.

Therefore, on the 10th birthday, the penny will have doubled 9 times (since it doubles on each birthday except the first), so the total amount of money you will have is: 512 pennies on your 10th Birthday

Answer 2

20

Explanation:

You have to multiply 10 by 2, which the ten represents ur 10th birthday, and the 2 represents the amount doubled. 10+2=20
